Investigators have linked a seventh homicide, as well as three additional shootings that left two people hurt and a vehicle damaged, to the man they are now publicly referring to as the “serial street shooter.”

The Phoenix Police Department says 55-year-old Krystal Annette White was likely the second casualty in a three-month shooting spree that is now tied to incidents between March 17 and June 12. White’s body was discovered about 4:30 a.m. April 19 in the 500 block of North 32nd Street.

The addition of White’s case expands the geographical scope of the investigation considerably. While the suspect was only initially tied to four shootings that killed six people in Maryvale, the addition of White’s case links the shooter to a crime scene clear across town.

In his first public event since last week’s deadly ambush of Dallas police officers, Donald Trump on Monday called for an end to hostility to the nation’s law enforcement and insisted that he is the “law and order” candidate in the presidential race.

Speaking to an invited audience in what is expected to be battleground state this fall, Trump was here to promote his proposals on improving care for the nation’s military veterans. But the presumptive Republican presidential nominee, who read from a teleprompter, kicked off his remarks with a lengthy statement of support for the country’s law enforcement officers amid turmoil prompted by a spate of deadly police shootings.

Trump called last Thursday’s ambush in Dallas, which left five police officers dead and several others injured, “an attack on our country.” He likened the current mood among many toward law enforcement officers to the harassment and hostility faced by soldiers serving in the Vietnam War, which he described as an “ugly chapter” in the nation’s history.

“America’s police and law enforcement personnel are what separate our civilization from total chaos and the destruction of our country as we know it,” he said. “It is time for hostility against our police and against all members of law enforcement to end and end immediately, right now.”

Speaking to about 2,000 people at a rally in what is expected to be a battleground state this fall, the presumptive Republican nominee had been trashing President Obama’s handling of terrorism and offering a critique of the ability of his likely Democratic rival, Hillary Clinton, to keep the country safe, when he veered off written notes.

“Saddam Hussein was a bad guy, right?” Trump declared. “He was a bad guy, really bad guy. But you know what he did well? He killed terrorists. He did that so good. They didn’t read them rights. They didn’t talk. They were terrorists. It was over.”

Trump, who supported the Iraq War in the early months of the conflict but later disavowed it, also criticized the United States’ decision to invade Iraq and remove Hussein from power, suggesting it “destabilized the region.”

“Today, Iraq is the Harvard for terrorism,” Trump said. “You want to be a terrorist, you go to Iraq. It’s like Harvard, OK?”
